// packet handler typedef void (*btstack_packet_handler_t) (uint8_t packet_type, uint16_t channel, uint8_t *packet, uint16_t size);

I don't understand "we don't have the permission to open the file btstack/include/btstack/btstack.h." it's e.g. here: https://code.google.com/p/btstack/source/browse/trunk/include/btstack/btstack.h
